Technology Update

industry requirements from basic frost protection to product melt-out. Heating management is achieved by fixed or variable control systems, including temperature monitoring and low temperature warning systems. More sophisticated centralised control systems that incorporate PLCs and 4-20mA outputs can be supplied. The high purity process pipework is manufactured using the latest automated orbital welding techniques. Finished

products conform to ASME BPE 2000 specifications, and comply with MCA and FDA standards.

High quality heated process pipework systems A joint venture operation between UK companies Norward Process, specialists in the production of high purity process pipework, and Inditherm Industrial, a provider of heating solutions, has led to the production of quality heated pipework systems. These systems are used in the pharmaceutical, food, beverage, confectionary and chemical industries. Norward Process pipework products can now be fitted with Inditherm Conductive Polymer Technology (CPT) heating. This is a carbon based flexible polymer that generates uniform heat over the entire surface area, eliminating both cold spots and localised overheating. The heat is generated via a low voltage supply which is both safe and efficient.

› Pipe from Norward Process can now be fitted with Inditherm Conductive Polymer Technology heating The flexible heating mat can be wrapped around pipework, as well as being cut to shape for use on associated equipment including valves and pumps. It is held in position with insulation that is banded on the outside. Alternatively, when required for use in hygienic conditions that are subject to water- jet cleaning, insulated heated pipework can be clad with an outer metal sheath made from high grade stainless steel, without seams or rivets. Ends are capped with stainless steel, with hygienic end fittings used to interconnect between pipework. Integrity of the inner pipework joint seals is maintained, and an external seal is provided for protection against water/dirt ingress. Inditherm’s CPT heating system can be used to replace traditional technologies of jacketed hot water or electrical trace heating, and provides temperature control to ±1ºC. This makes it suitable for process
